Who was the first Prime Minister of Canada?

John A. Macdonald was the first Prime Minister of Canada, serving from July 1, 1867, when Canadian Confederation was established, until 1873, and then again from 1878 until his death in 1891. He played a crucial role in the founding of Canada and was instrumental in the creation of the Dominion of Canada, which united the British North American colonies. His leadership helped shape the country's early political structure and policies, making him a significant figure in Canadian history.

The other figures mentioned served as Prime Minister at different times and contributed to Canada's political landscape, but only Macdonald holds the distinction of being the very first to assume the role.
